Be it known that I, ISRAEL B. BLUMENBERG,

a citizen of the United States, residing at WVashington, in the District of Columbia, have in vented certain new and usefullmprovements in VaponGenerators and Motors, of which the following is a specification, reference being had therein to the accompanying drawings. My invention relates to improvements in IO the method of resolving volatile fluids into power-vapor, as well as in the form, construction, and arrangement of power-vaporgenerators, steam-boilers, and furnaces, and in the mode of adjusting and connecting the several parts one to the other; and it consists in ad justing and securing a bell or dome shaped empty vertical cylindrical vapor-generator having a circling flange on the lower rim, and provided with a vapor-gage, a safety-valve, 2o i'nductioupipe terminating in a rose on-the inside, an eduction-pipe and protnberances on the inner wall, on the upper side of a disk orplate of metal containing numerous long slim tubes, secured therein and extend- 2 5 ing outward, and closed at the outer ends, se-

cured in a substantial manner on the open upper end of a steamboiler, arranged over and' forming part of a heating-furnace, and provided with a corrugated bottom with an- 0 nular water-legs, or a coil-pipe extending from the bottom down into the furnace beneath, the idea being to present as great a surface as possible to the fire in the furnace for heating purposes, the said boiler being provided with an induction-pipe for water, a waste-pipe to draw off, a steam-gage to test the pressure,anda blow-off pipe to relieve the boiler of air. It further consistsin providing protuber- 0 ances on the inner wall of such vapor-generators for supporting in place removable diaphragms, and in securing thereon a metal lat tice or wire diaphragm, a metal plate or disk containing numerous short open'tubes, or a 5 series of Vshaped brackets, when it is desired to increase the power without increasing the'eitter'nal diameter or the consumption of fuel, all of which is more particularly shown and pointed out in the accompanying drawin-gs and specification.

d is a vertical cylindrical vapor-generator, of metal of great strength, the height being equal to about from one and onehalf to two and one-half diameters, constructed in almost any form, preference being given to the invcrtcd bell shape, open at the bottom, and having an external flange, (1, around the edge of the open end, perforated for bolts '1', provided with a vapor-gage, c, a safety-valve, c", and internal protuberances, c, on which the diaphragnis d? and d" and brackets (1 rest or are secured. In the top of the generator (I is introduced a general supplypipe, 0, having a distributirig-nozzle, and provided with a. check-valve, e": also a vapor-edi :tion pipe,f, provided with a throttle-valve.f theformer connecting the generator with the reservoir F through the pump 71, and the latter connecting the generator with the motor-engine.

Connected by one end to the supply-pipe o and by the other to force pump la is a general supply-pipe. 1:, having a stop-cock and check-valve, a, through which the volatile fluid is carried from the reservoir I through pump it to the generator (I, and the flow thereof is regulated by the stop-cock c", the checkvalve preventing the generated vapor from passing back into the pipes. The open part of the generator (I rests on and is secured by bolts 73 to a tube-plate, I which is as large in diameter as both the generator (Z and its flange d. The plate B is a circular disk or diaphragm, of metal of great tensile strength, of the same diameter as both the gcneratord and its flange (1, into which is secured. by their open ends, a large number of long slim tubes,

c, flush with one side and extending their full length beyond the other, and closed and made The disk 13 serves as a bottom to the vapor-generator d, and separates it from the steam-boiler y beneath, and is perforated, near its periphery,

its entire (jllClllllfClOllCC, with bolt-holes 0*,

by which it is secured both to the generator d and the steam-boiler g, into which the tubes 0 extend their entire length, by bolts 1. The under side of the plate B,with its myriad of tubes 0 extending full depth into the boiler 11, presents an extensive area to the action of the heat required to convert the volatile liquid into vapor. I call this plate and its tubes my tube-plate. In the simple generator the volatile liquid is thrown in a spray onto the plate B and into the mouths of the open tubes 0, and there being such an extensive heated surface a very large quantity of fluid is instantly converted into power-vapor, so that with a generator thirty-six inches in diameter and about two-thirds of the diameter in height, with tubes twenty inches deep, I can obtain from one to five hundred horsepower in vapor, using not to exceed ten pounds ofsteani-pressure for heating purposes; but when I increase my heating-surface by adding intcrnally-ad 'usted diaphragms or brackets, or both, as hereinafter shown, I multiply my power without increasing either the external dimensions or the consumption of fuel.

/is acylindrical boiler, constructed of proper material and of the same diameter as the generator (I, provided with an external flange, 0', around the open upper edge, perforated with bolt-holes, by which it and the tube-plate B and the vapor-generator d are secured together, a blow-pipe, 7;, a stcanrgage, It, a water-tap, t, and a water induction pipe, I. This vessel is necessarily but a little deeper, vertically, than the length of the closed tubes 0 in the tube-plate L. which protrudes into it, as shown in Figs. 1, 2, 23, fl, and 10, and may have a plain bottom, as shown in Fig. 2, a corrugated bottom, as shown in Fig. 3, or a corrugated bottom with annular water-legs gflsurrounding the furnace, as shown in Fig. 1, or atubulatcd bottom, as shown in Fig. 9, or, as shown in Fig. 10, it may have protruding from the bottom at one point a coil-pipe, g extending into the furnace and again entering the boiler. These various forms of boilers are suggested by the necessity of presenting as great a superficial surface to the action of the fire as can be had without materially increasing the area to be occupied by the boiler and generator or increasing the size ofthe furnace, the idea being as well the economy of fuel as of space. By using the corrugated bottom, or the boiler with a corrugated bottom and annular waterlegs, or the modifications shown, I materially increase my heating-surface without necessarily increasing thequantity of wa ter or fuel requisite to accomplish the purpose-4. 0., generating a suflicient moist heat to instantaneously vaporize the fluid as it is injected into the vapor-generator.

m in in? are furnaces or lire-places, differing only in detail of construction, the furnace at being only the ordinary stove-furnace provided with a grate, m, aslrpit, draft, dampers, &e., appurtenant to such furnaces. The furnace in is construct ed within annular water-legs extending down from the boiler g, while the furnace or is walled on the inside with fire-brick. These various forms or classes of furnaces have all the usual and most improved accessories pcrtaining to furnr ces. The furnace 777, m, or m selected and the boiler are adjusted and firmly secured together by any approved mode, the tube-plate B put in place on the open upper end of the boiler g, the tubes 0 extending down into the boiler, the vapor-generator d placed on the top of the tube-plate B and secured to the boiler g by bolts i in the flanges cl and c" and the plate B, the several joints having previously been carefully packed by any suitable packing, to preventany possibility of leakage either of the vapor or the steam. I prefer, however, to use the packing invented by myself and secured to me by Letters Patent No. 230,996, and dated August 10, A. D. 1880, and the whole set up and adjusted as indicated, and connected with the pump 71 and engine A.

IOU

The volatile liquid is automatically pumped into the generator as required, and the vapor is generated by moist heat from the boiler g continuously, as hereinafter described.

The induction-pipe 0, preferably a copper pipe of about seveneighths of an inch in diameter, secured in the crown of the vaporgenerator, is provided with a check-valve, 6, near the shell of the generator, to prevent the vapor from forcing its way out through the supply-pipe e, and thence to the pump h, and terminates in a rose, 6", within the generator, and is connected with the supply-piped. The rose a? is of any approved design that will best perform the function of distributing the volatile liquid in a spray or shower, as desired, and over the most extensive surface. The supply-pipe e is anordinary metal pipe about seven-eighths of an inch in diameter, provided with a stop-cock or globe-valve, e, to regulate the flow of the liquid, and isv attached at one end to the induction-pipe e and by the other with the pump 72, and is used for conducting the volatile liquid from the pump to the generator. I

The eduction-pipe f should be constructed of metal of considerable tensile strength, may be of any diameter requisite, and is provided with a throttle-valve, f through which the fiowof the vapor from the generator to the cylinder f of the engine A is regulated. This pipe is secured by one end to the generator by a vapor-tight joint and by the other end to the engine-cylinder by a similar joint.

0 is an ordinary va-porgage to show the power-pressure.

c is an ordinary weighted safety-valve, connected by a pipe, 0 with the surface-condenser E, or any other condenser. used, so that if by any chance there should be too heavy a head of vapor in the generator it could escape through the safety-valve to the condenser, be immediately convertediuto fluid, and avoid accident.

c are protubcrances on the inner wall of the generator (I, which support the auxiliary diaphragms or brackets which it may be deemed necessary to adjust therein, as hereinafter explained.

- It is a well-known and recognized fact among those informed on the subjcctthat in vapor generated by heat there is a certain amount oflatentheat, which, when properly husbanded, may be utilized ingenerating other power. To be better understood I wish to say, a unit of water at its boiling-point requires 535.77 units of heat to convert it into steam at the same temperature as the water from which it was derived, while a unit of volatile liquid say, for instance, bisulphide of carbonat its boiling-point requires only86.67 units of heat toconvert it into vapor at the same temperature as the bisulphide of carbon from which it was derivedabout one-sixth of that required for water. i 7 Therefore bisulphide of 'carbon vaporized under heat generated by steam will carry off from four to six times as much heat as is requisite to vaporize and usefully employ the vapor. This heat I propose to use when I desire to multiply my power without increasing the external diameter of my generator, boiler, and furnace; and with this end in view I have devised several forms of adjunct metal diaphragms and brackets, which I adjust within the vaporgenerator d, which occupy no material space and do notinte'rfere with the free expansion or action of the vapor.

These features are set forth in an application for another patent, in which they are claimed; but to show their relation to this character of generator I will outline them here.

at is a light metal plate or disk, of the diameter of the interior of the generator cl, into which is securely fastened one end of a large number of open tubes, (2, considerably larger in diameter, though shorter, than the tubes 0.

d" is a V- shaped bracket having projections on the lower edge and a flange for securing it in place, and d is a metal screen, of the same diameter of the interior of the generator (I. When I desire to increase my power, as stated, I adjust the tube-plate (i within the generator (2, by resting it on the projections c therein, or adjust a series of brackets, (1*, around the interior of the generator, as shown in Figs. 4 and 5; or I adjust the screen (1 within the generator; or, if I prefer it, I employ any two or more of these, which are heated by the latent heat from the vapor, so that when the fluid is thrown upon them in a spray it is either vaporized or heated to that degree that it is read ily vaporized when it reaches the tube-plate I3. By this means I obtain a surface for vaporizing an additional quantity of fluid without employing any additional fuel or external space. v

k and k are the ordinary steam-gages, used to indicate the pressure of the steam in the boiler.

Z is a small with water. ing off the water from the same. k is an-ordinary escape or blow pipe and cock, all being shown in Fig. 10. q

A is a motor-engine, vertical or horizontal, having a band-wheel, a, and a balance-wheel, a and in addition to its other functions, through a reciprocating rod, h, attached to an eccentric and connected with the pump h, it automatically supplies the fluid to the generator d. Connected with the engine by an exhaust-pipe, 0, is a surface-condenser, E.

E is a surface-condenser, fully described in thespecification to Letters Patent No. 238,754, granted to me March 15, A. D. 1881, and its function is to condense the vapor after it has been used in the cylinder f, before it is returned throughthe pipe 0 to the reservoir F, and is attached to the engine by the exhaustpipe 0. \Vhile I prefer this style ofcondenser, I do not confine myself I exclusively to its use or to anyform, using as well the coil-pipe or pipe for supplying the boiler' 1 is a waste-pipe or tap, for draW- sector any approved form in use. 7; are blow-pipes on the condenser B, through which an accumulation of air or vapor is blown off.

F is a liquid-rcservoir. It may be of any form or size, and of any suitable material. it is provided with an induetioirpipe, c, an eduction-pipe, o, a blowpipe by which it is relieved of pressure from the accumulation of air, and an induction funnel and cock, 7.

h is a force-pump operated through the rod h by an eccentric on the engine A. By this pump the fluid is drawn from the reservoir F through the pipe 0, and injected into the empt'y chamber of the vapor-generator (I, through the pipe 0 c and distributing-rose (f.

The various parts having been adjusted and connected as herein shown, the rescrvoirsupplied with fluid, and steam having been generated in the boiler and brought in contact with the under side of the tube-plate l3 and the outsides of the tubes 0, heating them to a temperature sufficient to vaporize the fluid, the volatile liquid is injected into the empty chamber of the generator (7, through the supply-pipe c, and by the rose 0' thrown in a shower or spray onto the tube-plate l3 and into the open mouths of the tubes 0, or onto the auxiliary parts (Z d d", and the tube-plate B, where it is instantly converted into powervapor and conducted by the eduction-pipe f to the engine-cylinder f, where, by direct impact on the piston f" of the motor-engine A, which is actuated and which through an eccentric thereon actuates the pump 71, which draws the volatile fluid from the reservoir F through the pipe 0, and automatically supplies it to the generator (I, the vapor having performed its office, passes from the engine-cylinder 1" through the exhaust to the condenser E, where it is again converted into fluid and returned to the reservoir F, to be again used. The operation being continuous, the liquid maybe used adt'afinitunnwithout loss or waste, and there being no escape for the steam, there is no loss of watera barrel of water per day being sufficient to run an engine of twenty to one hundred horsepower, and, after the firstheating, as the boil ers are not replenished by cold water, it will require less fuel to keep up the temperature necessary to generate vapor.

I am aware that numerous attempts have heretofore been made to advantageously employ vapor generated from bisulphide of carbon and other volatile fluids as an active motor agent, and many devices have been devised to that end. The ditlieulty heretofore has beento so construct the machinery as to secure a steady, uniform, reliable power, and at the same time economize fuel, space, cost of machinery, and money, as well as to produce something that may be introduced into everydayuse. By my invention and several im- PI'OVGlilClliS 011 ill) lllOiTOT-DOWCl' vapor-generating devices and methods of generating and utilizing suchvaporsJclaim thatlhave accomplished this, in that, bymy tube-plate B, within an apparently limited space, I, on the one side, present an extensive surface to the action of the heating medium, steam, and 011 the other side an extensive area raised by steam to a temperature to between four and live times greater than is actually required to vaporize the volatile fluid, and that by injecting the volatile fluid in a continuous shower or spray into the empty heated generating-chamber, enlarged by the many tubes 0, and the tubeplate 13, and, when desired, by the adjunct (1iaphragms d (1, and d", therein secured, laugment my power to almost any reasonable extent without incrcasing the consumption of fuel, keeping up at the same time a uniform power, be it greater or less; and then, by preventing loss or waste of the vapor generated by constructing a reservoir of fluid packing wit hin the packing-box oftrhe engine-cylinder, and packing the several connectingoints with my '"joint-packing, which practical experience has abundantly demonstrated will wholly seal up the parts and prevent the escape of the vapor; and, by condensing and reusingthc volatile fluid, safety, utility, and economy are secured.

The above-described method. of i'itilizing volatile fluid, and in packing the joints as well as packing the engine-cyliiuler, are shown in various modified forms and claimed in other applications for patents which I now have pending and in patents granted to me. I do not therefore claim them, broadly, in the present application.

.By the use of the boiler with corrugated bottom, or the boiler with corrugated bottom and annular water-legs, or the modifications thereof, I present no inconsiderable steamboiler area to the action of the tire for heating purposes, I require less fuel to generate steam by continuously using the same heated water for supplying the heat required for generatin g the power-vapor, and I economize the fuel required or necessary for raising the water from its then mean temperature to that of boiling water or steam.

As compared with the cost of steam, exclusive of the difference in the cost of the two characters of motors, &c., as well as the difference in the space occupied by the two classes oftnotors, as another item of economy I may suggest, iirst, that the specific heat required to raise bisulphide of carbon from a comparable to a boiling-point, water being 1 or unit, is 218967. In other words, it takes only about one-fourth as much heat to raise bisulphidc of carbon or similar volatile fluids from a common temperature to its boilingpoint as it does water to its boiling-point, which of course cuts off at least three-fourths of the fuel demanded by steam for that part of the work; second, the latent heat of vaporization2'. 0., the amount of heat required to convert a unit of a body, at its boilingpoint, from the liquid to its vapor state, both too I SO

liquid and vapor being at the same tempera- -tureof bisulphide of carbon isonly one-fifth that of water; hence one-sixth of the amount of heat required by water will do the same work with my motor third, the loss of heat by radiation from my motor willbe very much less than where steam is employed, for two reasons: first, the lower temperaturethat-is to say, the 180 of heat required to vaporize the fluid used in vapor-motors as compared with the 240 to 7 00 or more required for steam-engines, as the ratio of radiation advances rapidly as the temperature rises, and second, the smallness of my generator, as compared with steam-boilers, presents much less surface for throwing off heat and to theconsumer these are matters of grave importance; fourth, in my generator the bottom tube-plate, B, with its myriad of small tubes 0, is heated to a temperature of from 212 to 700 Fahrenheit and greater, heating the empty chamber or spray, is brought in contact with the heated metal diaphragms, the temperature of the fluid is raised either to the vapor state, or to that degree of temperature that, when broughtin contact with the tube-plate B, it is made a' power-vapor at a lesser cost of heat.

The device which I show as my vapor-motor generator is simple in construction, easily handled, and equally as tractable as steampower devices, and, I claim, more safe, for the following reasons: By simply opening the valve 6 andincreasing the supply offluid, I can raise my power from zero to from one to fivehund red pounds pressure; with a steam-pressure, for heating purposes, of from three to ten pounds, and by simply shutting off the supply of fluid, Iagain reduce the power to zero, and that, too, without changing the steam pressure; but should it so chance that too great a pressure of vapor is generated in the generator, the safety-valve will give way and permit them por to discharge into the condenser E, when it is again condensed into a harmless fluid; but should an explosion take place there are no ponderous metal boilers to be torn, and, to gether with superheated steam and boiling water, he made the instruments of death and destruction.

A patent, No. 236,411, has already issued to me on an inchoate idea of this invention, wherefore I do not purpose claiming, broadly, what is herein described; and while in my drawings and specifications I showa reservoir of fluid packing in my engine-cylinder, I do so merely to show its location and the mode of confining the vapor. Having shown and claimed this feature in another applicationallowe to me, I do not claim it herein.
